{"title":"Letter to the Editor: Rethinking The Cost Of Antipsychotic Treatment: The Average Cost Of The Drugs Used In Turkey In 2020.","authors":"Mustafa Yıldız,&nbsp;Emre Osman","doi":"10.5080/u26315","DOIUrl":"https://doi.org/10.5080/u26315","url":null,"abstract":"&lt;p&gt;&lt;p&gt;Dear Editor, The costs of antipsychotic drugs (APDs) used in the treatment of mental disorders with psychosis are mentioned in treatment guidelines (APA 2021, NICE 2014). While the American Psychiatric Association guideline states that every specialist should make decisions according to the rules and conditions of their country and their region, the National Institute of Health and Clinical Excellence guideline emphasizes that drug costs must be taken into consideration in the treatment process. Classical or first-generation antipsychotic drugs (FAPDs) are relatively cheaper in terms of sales prices compared to atypical or second-generation antipsychotic drugs (SAPDs) with a slightly different effect mechanism. The price difference between the two drug groups can be so large that sometimes it may be necessary to consider whether the cost of a second-generation drug is worth its benefit. While deciding on the use of first-generation or second-generation drugs, a multifaceted assessment should be made, such as the patient's level of compliance with the treatment, the possibility of occurrence of side effects, the possible effects of these side effects on body health and treatment compliance, and whether or not the costs are covered. The most important criterion that determines the choice of medication for psychiatrists is of course the multi-dimensional benefit/harm ratio that the drug used will reveal in the long term. We think that in our country, which, in terms of economic indicators is not in a strong position as an importer of pharmaceutical raw materials from abroad, APDs' cost calculation should be considered because drug costs constitute an important part of the direct treatment costs of psychotic disorders in developing countries such as Turkey (Yıldız and Cerit 2006). We calculated the unit (mg) price based on the box prices of the APDs in use in 2020, thinking that it might work when calculating the cost of the illness using APDs as the main component of the treatment and calculated the annual average drug costs with the daily average dosage. Although the daily treatment dose varies with the stage of the illness and the individual characteristics of the patient, the average doses recommended for maintenance treatment were used here (Öztürk and Ulusahin 2018). The daily and annual cost calculations based on the assumption that the average maintenance treatment dose was used with the unit price obtained from (Drug Prices 2020) the drugs in the Turkish pharmaceutical market in September 2020 are shown in Table 1. A similar study was done in 2005 (Yıldız 2005). The purpose of this article is to redetermine the average costs of APDs in the Turkish pharmaceutical market every 15 years and to bring them to the attention of experts in terms of cost-effectiveness studies. When the costs in 2005 are examined, it is seen that the annual costs of the FAPDs were around 450 TRY, and the annual cost of oral preparations of SAPDs was 2,500 TRY (5","PeriodicalId":47266,"journal":{"name":"Turk Psikiyatri Dergisi","volume":"33 2","pages":"146-148"},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40177547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
